How to change the size of AnimatedFAB

### AnimatedFAB size

How do I change the size of the AnimatedFAB?
The size prop used with the normal FAB does not work, and playing around with the style does not work properly either.

Start at the AnimatedFAB component entry point and inspect how its size prop and style are handled. Reproduce the reported behavior with a custom size, then determine the expected supported way to resize the component and verify that the size change works without breaking the animation.
